Reading about the new math discoveries made with Lean, and having interviewed Sir Timothy Gowers at @gosimfoundation Paris about his work at Cambridge and the Collège de France on it, I made a note to myself to check out Lean. And last night, I did, counting the ways a river can cross a road. It's a problem posted by the Soviet mathematician V.I. Arnold, and my older brother counted some of n on BESM-6, a Soviet supercomputer my mom used to program. It's a long way from punch cards and line printer output to the beautiful visualizations and fast Lean transfer matrices! Read the blog: chief.sc/arnold-meanders/

A Terminator sequel where he goes to 1907 Vienna and kills enough of the applicants to the Akademie fΓΌr Bildende KΓΌnste to ensure Hitler is accepted after all.

The first tour had 111 applicants, and Hitler passed, but failed the second, and only 28 were admitted.

Amazing to see the strait of Hormuz win a majority in Congress!

I was in the original beta for @Waymo. And now the seats of its Jaguars are polished to the gloss by the thousands of the behinds of the startup founders and developers and PMs.

My favorite airport hack: Pick up arriving passengers at the departure level. Always deserted.

OSS AI FTW!
It’s done! Marin’s Mochi 535B-A23B finished its main pretraining phase this morning. 18T tokens! Long context this weekend, SFT over the next week or so. Hoping to release checkpoints next week. Some EU paperwork first. mumtracker.exe.xyz/hero-run-…

Received a pass long time ago to Reverie from @lancedb and stopped by as it was near Data Outpost, and it turns out it was not a pass but an approval to buy one! They even called me shortly after and asked whether I will attend, which I assumed was a check for an invite so felt obliged to come by. In my 15 years running events it’s a first one! Fortunately it’s an easy walk back.

Funny how I have an actual ticket and when they scan it it shows undefined and they explain people were supposed to pay after getting approved! Could have reported from the first Reverie ever but I guess not.
